Answer:
5/4 (d)
Step-by-step explanation:
wed- 610
mon - 488
Ratio = Wed/mon = 610/488
(610/2)/(488/2) = 305/244
305 = 61 x 5
244 = 61 x 4
cancelling out the 61 on both number = 5/4
Answer:
It should be C: 5:4
Step-by-step explanation:
because Wednesday=610
Monday=488
Ratio = Wed/mon = 610/488
610/488 = 5/4

For question 6 the answer is 91 just add the numbers
Sam uses text messaging to communicate. The table below represents a proportional relationship between the number of words Sam texts, y, and the time, in minutes, he spends texting, x.
The equation that represents the table is y =
x.
If Sam can text 360 words in 6 minutes, the new equation that would represent this relationship is y =
x.
Answer: 56 and 60.
Step-by-step explanation:
First find the number of texts per minute. 112 divided by 2 is 56. So Sam texts 56 words per minute. Since y = (blank)x, you can plug in the values which get you 56=(blank) times 1. 56 divided by 1 is 56. So for the first question, the answer is 56.
For the second question, you can do the same process and divide 360 by 6. This gets you 60 words per minute. Same equation as the previous question, so just plug in the numbers and you get y=60x.
can you please help me
Use Pythagorean theorem
a² + b² = c²
30² + b² = 78²
b² = 5184
b = √5184
b = 72
Answer:
I think its 72
Step-by-step explanation:
Im not 100% but i think you have to add every side and you have to comlite 180 so 180-78-30=72.....
Im sure that this is what you do with the corners but it could be the same for the sides maybe
you bought a magazine for $5 and four erasers. you spent a total of $25. how much did the eraser cost?
Answer:
1 eraser = $54 erasers = $20Step-by-step explanation:
Given that,
→ Magazine = $5
→ Total cost = $25
→ 1 eraser = x
The equation will be,
→ 4x + 5 = 25
Now the value of x will be,
→ 4x + 5 = 25
→ 4x = 25 - 5
→ x = 20/4
→ [ x = $5 ]
Hence, value of x is $5.
Diagonals of a trapezoid intersect each other at point E, and the extensions of the legs of the trapezoid intersect each other at point F. Prove that line EF bisects the bases of the trapezoid.
PLEASE HELP, IT’S DUE TOMORROW. 50 POINTS AND BRAINLIEST.
Answer:
See Below.
Step-by-step explanation:
Let the intersection point above E be K, and let the intersection point below E be J.
Since ABCD is a trapezoid:
\(\displaystyle AB\parallel DC\)
Therefore:
\(\displaystyle \angle AJF\cong \angle DKF\)
And:
\(\displaystyle \angle DFJ\cong \angle DFJ\)
So, by AA-Similarity:
\(\displaystyle \Delta DFK\sim \Delta AFJ\)
CPSTP (Corresponding Parts of Similar Triangles are Proportional):
\(\displaystyle \frac{KD}{JA}=\frac{FK}{FJ}\)
Likewise, do the same to the other side. Since AB is parallel to DC:
\(\displaystyle \angle BJF\cong CKF\text{ and } \angle CFJ\cong \angle CFJ\)
Hence:
\(\Delta CFK\sim \Delta BFJ\)
By CPSTP:
\(\displaystyle \frac{KC}{JB}=\frac{FK}{FJ}\)
Substitution:
\(\displaystyle \frac{KD}{JA}=\frac{KC}{JB}\)
Since AB is parallel to DC:
\(\displaystyle \angle CDB\cong \angle ABD\)
By vertical angles:
\(\angle DEK\cong BEJ\)
Hence, by AA-Similarity:
\(\Delta DKE\sim \Delta BJE\)
CPSTP:
\(\displaystyle \frac{KD}{JB}=\frac{KE}{JE}\)
Likewise:
\(\angle DCE\cong \angle BAC\)
And by vertical angles:
\(\displaystyle \angle CEK\cong \angle AEJ\)
Hence:
\(\Delta CKE\sim \Delta AJE\)
CPSTP:
\(\displaystyle \frac{KC}{JA}=\frac{KE}{JE}\)
Substitution:
\(\displaystyle \frac{KD}{JB}=\frac{KC}{JA}\)
Now, we have obtained that:
\(\displaystyle \frac{KD}{JA}=\frac{KC}{JB}\)
And:
\(\displaystyle \frac{KD}{JB}=\frac{KC}{JA}\)
In the second proportion, multiply both sides by JA:
\(\displaystyle \frac{KD\cdot JA}{JB}=KC\)
In the first equation, multiply both sides by JB:
\(\displaystyle \frac{KD\cdot JB}{JA}=KC\)
Substitute:
\(\displaystyle \frac{KD\cdot JA}{JB}=\frac{KD\cdot JB}{JA}\)
Cross-multiply:
\(JB\cdot KD\cdot JB=JA \cdot KD\cdot JA\)
Cancel out KD and simplify:
\(JB^2=JA^2\)
Therefore:
\(JB=JA\)
And using the first proportion again:
\(\displaystyle \frac{KD}{JA}=\frac{KC}{JA}\Rightarrow KD=KC\)
Hence, EF bisects AB and DC, the bases of the trapezoid.
Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅

Answer:
option B , I saw this question on a math website thats why its B
Answer:
It would be D.
Step-by-step explanation:
You would count each square and multiply it by 18. It is like that because they are cubes. There are 16 full cubes. 16x18=288. Those 2 triangles would be a full square. It would equal 18. 288+18=306. But now you square it which would equal 612. A.K.A

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.
What is the area of the curved surface of the trash can she will need to decorate?
A trash can with radius 4 inches and height 12 inches.
12 in =30 cm
4 in = 10 cm
area of 1 circle= 3.14×10×10= 314 cm²
area of 2 circle= 314×2= 628 cm²
if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)
length of rectangle = circle circumference
= 2×3.14×10
=62.8 cm
area of rectangle= 62.8 × 30 = 1884 cm²
total area= 1884 + 628 = 2512 cm²

The tens digit is three less than the units digit. If the digits are reversed, the sum of the reversed number and the original number is 121. Find the original number.
help!!!!!
Answer: 47, 74
Step-by-step explanation:
Let x = units digit
x – 3 = tens digit
Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)
Equation
The reversed number plus the original number equal 121.
10(x) + (x – 3) + 10(x – 3) + x = 154
10x + x – 3 + 10x -30 + x = 121
22x – 33 = 121
22x = 154
x = 7 (units digit)
x – 3 = 4 (tens digit)

When tossing a two-sided, fair coin with one side colored red and the other side colored green, determine P(green).
2
one half
green over red
red over green
Answer:
one half
Step-by-step explanation:
Total number of outcomes = 2
Event of obtaining green = 1
Probability of obtaining green= one half
The solution is Option B.
The probability of getting green P ( green ) = 1/2
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability of getting a green while tossing a coin be P ( green )
Now , the total number of colors in the coin = { red , green } = 2
The probability of getting a green = green / total number of colors in the coin
Substituting the values in the equation , we get
Probability of getting a green while tossing a coin P ( green ) = 1/2
Probability of getting a green while tossing a coin P ( green ) = 0.5
Therefore , the value of P ( green ) is 1/2
Hence . the probability is 1/2

Could anyone help me with this problem, Quickly Please...
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

About 71% of Earth’s surface is covered in water.
Question 1
Part A
If Earth's surface area is about 196,900,000 square miles, about how many square miles are covered in water?
Enter the correct answer in the box.
Part B
About what percent of Earth’s surface is not covered in water? How many square miles is this?
Enter the correct answers in the boxes.
Answer:
A. 139,799,000 square miles
B. 57,101,000 square miles
Step-by-step explanation:
71% ÷ 100 = 0.71
0.71 x 196,900,000 = 139,799,000
100 - 71 = 29
29 ÷ 100 = 0.29
0.29 x 196,900,000 = 57,101,000

Answer:
107°
Step-by-step explanation:
the arrow is in between 6 and 8, but it's too thick to see seven underneath it, but I've zoomed in. it's also 107° rather than 73° because the angle is larger than 90° and starts on the left
As in how to determine it, first look at which side it's on first, if the Angle is bigger than 90° (the corner of a square) and which side it's on, if it's on the left it means u are using the top row of numbers, if it's on the right but at 107° however, it means u are using the wrong row of numbers.
